To all whom it may concern:

Be it known that I, BENJAMIN S.

My invention relates to an improvement in burners for vaporheating-stoves; and my invention consists in features of noveltyhereinafter fully described, and pointed out in the claim.

Referring to the drawings, Figure I illustrates a horizontal sectiontaken on line I I, Fig. II, through the burner, a portion of theburner-cap being also shown in horizontal section. Fig. II illustrates avertical section taken on line II II, Fig. I.

In the drawings, 1 represents the mixing chamber or base of a burnerhaving a central opening 2 and provided with a trough 3.

4 designates the inlet-pipe leading to the burner and opening into thetrough 3. The mixin gchamber is provided with outer flanges 5 and innerflanges 6 on each side of the trough 3, and on these flanges theburner-cap 7 rests. The burner-cap is provided with flanges S and hasouter jet-holes 9 and inner jet-holes 10.

11 designates an inner grate that rests upon the flange 6, the centralopening of which is directly above the opening 2. This grate issurmounted by a vertical cylinder 12.

13 designates an outer grate, which rests upon the flange 5 andsurrounds the burnercap 7. This outer grate is surmounted by an outercylinder 14.

The vapor enters the burner through the pipe 4, passing into the trough3, and from the trough passes through the jet-holes 9 and of theburner-cap, where it is burned. The passage of the air into and throughthe burner is indicated by the arrows in the drawings. One current ofair enters the burner through the opening 2, a portion of it ascendingdirectly through the inner cylinder 12, while the remainder divergesfrom an upward direction, passing through the openings of the innergrate 11. The other current of air enters the burner through the outergrate 13, where it comes in contact with the flame of the burner anddescends through the outer cylinder 14.

I claim as my invention- A vapor heating-stove comprising a main burnerhaving a central opening, the inner and outer grates, the inner andouter cylinders mounted on their respective grates, and the cap havinginner and outer flanges provided with jet holes; substantially asdescribed.
